Too many open files error....how to check?

[cbotiza]

Hi there,

When running my (I/O intensive) code on SUSE Linux 10, I sometime come accross a "Too many open files" error. I am sure there is a bug in my code, but how would I best approach this?

For example, what's the command / tool to report the number of open (file) handles?

Thank you

You can increase the limit of max files in /proc/sys/fs/file-max.
First check the current value with "cat /proc/sys/fs/file-max".
For example, to increase the value up to 24724 type this command (as root):

echo 24724 > /proc/sys/fs/file-max

Try to follow the UNIX principle of programming by not making any changes to other programs in order to make ur code work. That limit on maximum number of open file handles exists for a reason...
